AbstractInformation about the find of Primula macrocalyx Bunge in the Tyumen Province is given. On the territory of the province this species was first found by P.N. Krylov in 1937. Since then, no new discoveries have been made, and the primrose was considered an extinct species. In May 2017 the growth of this species was discovered by us in the Zavodoukovskiy district. This is one of the northernmost locations of P. macrocalyx in Western Siberia. A large population has at least a thousand clones on an area of about 4 hectares. Recommendations are given for the inclusion of the P. macrocalyx in the list of species to be included in the Red Book of the Tyumen Province.
